[1] At an early age, Bullaker was sent to the English College at St-Omer, where he may have studied for some time or simply made a spiritual retreat.

[1] Under the guidance of Alexander Baker, Bullaker entered the Franciscan order at Abrojo on the Feast of Corpus Christi in 1622.

Nothing could be proved against him at trial, and a supposed missal in his possession, offered as evidence, was shown to be a secular book on Spanish history.

In 1641, the Franciscan provincial, George Perrot, gave him permission to move to London and work among the poor Catholics there.

[1] On 11 September 1642, Bullaker was seized by James Wadsworth while celebrating Mass in the house of Margaret Powell.
